Abstract: ABSTRACT OF THE DISCLOSURE Dehydrated  liposomes  are  prepared  by  drying  liposome preparations under reduced pressure in the presence of one or more protective sugars, e.g., the disaccharides trehalose and sucrose. Preferably, the protective sugars are present at both the inside and outside surfaces of the liposome membranes.  Freezing of the liposome   preparation   prior   to   dehydration   is   optional. Alternatively, the protective sugar can be omitted if:   (1) the liposomes are of the type which have multiple lipid layers;  (2) the  dehydration  is  done  without  prior  freezing;  and  (3)  the dehydration  is performed  to  an  end  point  which  results  in sufficient water being left in the preparation (e.g., at least 12 moles water/mole lipid)  so that the integrity of a substantial portion of the multiple lipid layers is retained upon rehydration. Concentration  gradients  capable  of  generating  transmembrane potentials can be created across the liposome membranes either before  or after  dehydration,  and  the  transmembrane  potentials resulting from these gradients can be used to load charged ma-terials, e.g., drugs, into the liposomes.

Abstract: ABSTRACT OF THE DISCLOSURE        A method of preventing or retarding polymer build-up on the internal surfaces of polymerization reactors is provided by this invention.  Reduced build-up in vinyl chloride polymerization is obtained by having a phenolic compound coated on the internal surfaces of the reactor vessel and a water phase polymerization inhibitor either combined with the phenolic coating or added to the aqueous polymerization medium.  Optionally, a chelating agent is also added with the water phase inhibitor.  The process is further enhanced by the presence of water soluble dispersants such as polyvinyl alcohol and methyl cellulose.

Abstract: ICE DISPENSING MECHANISM                  ABSTRACT OF THE DISCLOSURE        An ice cube storage bin located beneath an auto-matic ice maker of a domestic refrigerator contains a pair of elongated ice dispensing rams that reciprocate along parallel lines, one of the rams moving toward the front of the bin, as the other moves toward the rear. The rams are interconnected by a pulley mounted belt that pulls one ram to the rear of the bin, as the other ram is pushed toward the front of the bin by a drive mechanism. The drive mechanism includes a pair of cam discs eccen-trically mounted in opposed relation on a common motor shaft located outside of the bin adjacent its rear wall. A pair of resilient lever arms, having their top ends pivotally mounted to the outside of the rear wall of the bin and their bottom ends pivotally connected to the rearward ends of the rams which extend from the interior of the bin, are engaged at their intermediate portions by the rotating cam discs wherein the rams are alternately pushed by the bottom ends of the lever arms toward the front of the bin.  The use of dual reciprocating rams, and the simplified push-pull drive means including the pulley mounted belt and the eccentric cam discs, provide a highly efficient and reliable ice dispensing mechanism.

Title: Enhancement of nucleic acid hybridization by anionic polymers
Inventor: BOGUSLAWSKI SOPHIE J
IPC: C12Q1/68
Filed: 1985-11-12
Granted: 1989-05-23
Abstract: ABSTRACT OF THE DISCLOSURE The rate of hybridization between two complementary polynucleotide segments in an aqueous medium is increased by the presence of the anionic polymers polyacrylate and polymethacrylate. The acceleration effect is particularly useful in nucleic acid hybridization assays involving immobilization of sample nucleic acids and the use of labeled probes. Nonspecific binding of probe to nitrocellulose supports is substantially lower in the presence of the present polymers than in the presence of the prior art accelerator dextran sulfate. Polyacrylate is particularly advantageous since it has been found to be effective at low concentrations and is significantly less expensive than the prior art compound.

Abstract: ABSTRACT OF THE DISCLOSURE     A rotary storage magazine usable below the level of the deck of a vehicle or structure, so that munitions may be stored and thereafter quickly delivered on an as-needed basis to an intermediate position for the reloading of a weapon.  This intermediate position can be on the deck, alongside the weapon to be reloaded, or else outboard of the weapon.  Our rotary storage magazine comprises fore and aft rotary support devices disposed below deck level a spaced distance apart, which distance is less than the length of the munitions to be stored.  The rotary support devices each have a plurality of support arms, such that a like number of munitions disposed in a generally parallel array may be cradled between corresponding support arms of the fore and aft rotary support devices.  The rotary support devices are rotatable together, and have a common axis of rotation.  We provide electric power for driving the rotary support devices in one rotative direction during the loading of munitions into the storage magazine, and for driving the rotary support devices in the opposite direction during the delivery of the munitions to the deck level of the vehicle.  We prefer to use releasable restraint arms on the support arms of the rotary support devices, such that the munitions will not be accidentally dislodged during rotation of the rotary support devices.          In the preferred embodiment, an elevator operational in timed relation to the rotary support devices serves as a munitions transporter that makes possible the ready loading as well as the rapid unloading of munitions from the rotary storage magazine.

Abstract: DRUM MAGAZINE     ABSTRACT           This invention relates to magazines for guns.  The drum magazine of the present invention comprises one or two generally cylindrical drums with openings for the exit of cartridges from within the drum.  A spring driven rotor within the drum carries two concentric rings of cartridges in a channel defined by the outer circumference of the rotor and the interior of the cylindrical drum wall.  The rotor engages the inner concentric ring of cartridges and each cartridge in the outer ring of cartridges is forced to move by contact with a cartridge of the inner ring.  During feeding, the cartridges are advanced as two rings until they meet the cam blade, which gradually forces the cartridges into a single column which moves approximately twice as fast as the velocity of the cartridges in the rotor.  When the last cartridge leaves the rotor during feeding and enters the exit passage, a follower arm is provided to continue to push the last cartridge out of the magazine.

Abstract: ABSTRACT OF THE DISCLOSURE           A breakwater comprised of an array of aligned perfor-ated-wall caissons having a slab bottom standing on a pervious rubble base and anchored by its own weight incorporates exceptionally heavy ballasting to ensure stability under attack by large waves, i.e. so that the ratio of maximum horizontal thrust force to net downward vertical force is below about 0.46.         The immersed wall height is much reduced so that the slab bottom lies below mean sea level about 1.3 to 1.7 times the height of the greatest wave predicted, lessening costs of construction and siting.  Efficient energy dissipation function is preserved by placement of augmenting mass below the height of the wave trough and by providing flow passages for jets directed by front wall ducts, avoiding increase of reflection coefficient.  The mass may be a pervious rubble store, or a lower-grade concrete cast about horizontal duct pipes extending into or wholly through the chamber, or may be metal slabs supported on racks, or may be apertured fairing bodies carried on the front wall. Double-sided breakwaters on coasts where wave incidence occurs only at high tides incorporate a large proportion of ballast mass; when oriented as groins to protect a river mouth, the porting of an intermediate wall allows sands to migrate freely through without accretion.         The rubble base comprises a core of gravel capped by larger rubble.

Abstract: ABSTRACT OF THE DISCLOSURE A fluid amplifier  is  used  in  a  pneumatic transducer to provide a control output pressure  in response to a pilot pressure provided as a function of a current signal.  The fluid amplifier includes a valve that opens a pressure  source  to  the  control port and also controls pressure  feeding through an exhuast passageway.  The amplifier valve is provided with a negative feedback arrangement as the exhaust back  pressure  increases  to  stabilize  the  operation and make the amplifier less sensitive. The pneumatic amplifier  is provided with a diaphragm arrangement that  results  in  increasing  exhaust  back  pressures tending to close the exhaust valve, rather than open the exhuast valve.  The negative feedback makes the valve more easily controlled and provides  for more stable operation.
